All queries in SWP, such as the result set of a ui:forEach, are computed
at once, i.e. there is no way to dynamically change the loop based on
things happening inside of the loop. There is no ui:while either - I
guess we just never had use cases for that. An alternative to while is
to do a recursive loop similar to functional programming, e.g. define
ui:MyElement which has a prototype with a ui:if... and then calling
<ui:MyElement /> again until the if is false. This approach however can
run into stack overflows, i.e. only works for certain traversal depths.

I would like to perform a while or do-while iteration with SWP. That
is, condition based rather than item based as in ui:foreach. I see
nothing in the manual about it so I'll look in the libraries but
thought I ask in parallel. I do not know if a ui:if and a ui:foreach
can produce the same results. Any pointers to examples or
documentation appreciated.
